I tried email but the message bounced.
On page 335 of PRINCIPALS OF NEURAL SCIENCE 3rd ed by Kandel,
Schwartz, and Jessell it says: "The only exception [to sensory systems
passing through the thalamus on the way to the cortex] is the
olfactory system, which transmits sensory information from the
periphery directly to the primitive cortex of the medial temporal
lobe."
I hope this is helpful.
